ZZYFGH Unique Jigsaw Puzzle, Impossible Challenge 141 Pieces Round Broken Color Changing Iridescent Acrylic Puzzles Game for Adult

I love this thing!The colors change depending on the surface assemble it on top of. It's surprising how reflective it is (you can see a chandelier reflected in the picture). I think there were a couple of pieces that could seem like they fit somewhere else (that's to be expected with acrylic puzzles), but it didn't take too long to identify them.Some light spoilers for the puzzle--There is a trick to distinguish which way the pieces are facing, and figuring that out will make this easier.Most of the edge pieces don't directly connect to each other, so you can't approach it with traditional methods.Heavier spoilers --The back of the puzzle is like a reflective tape. If you look at the pieces from the sides, you can see where the acrylic is relative to the tape.I'd recommend starting with the central piece of the puzzle and building out from there.

This was a lot of fun to pass an afternoon.

5th star would be reserved for better packaging. As it is plastic, the pieces run and scratch each other during shipment. The other round clear puzzle came very carefully packaged and was not scratched.As for the puzzle...Second hardest puzzle I've done. I had not seen a completed example, so I was completely in the dark. It was awesome.! Possibly the best edge work on a puzzle I've scene so far. Gives you a bit of a panic towards the end, wondering if all the pieces are there.Did it over a weekend working on it here and there.Would highly recommend.Please fix the packaging though.

Don't force any of the pices it could break eeasily.

This initially seemed impossible because there wasn’t a way to determine if it was the back or front of each piece! Now completed, it is a beautiful mirror with holographic colors that change with motion and light. It was fun but tricky to complete.

Clear acrylic puzzle listed as “impossible Challenge” but difficult for the wrong reason. The pieces are cut with a loose fit, thus do not lock together well. So many pieces are interchangeable. Poorly designed puzzle. They do give you a cheat sheet to follow if you want help….what fun is that?

This was a great Christmas gift however, a few pieces were chipped or broken so it wasn't as easy to complete
